MIT discovery unleashes solar revolution
First, MIT scientists recharged batteries wirelessly. Now they can mimic essence of plants' energy storage system.
In a leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, Massachusetts Institute of Technology (MIT) researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine.
Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. With today's announcement, MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.
Now a team led by Daniel Nocera at MIT has found a catalyst that uses cheap, abundant metals—cobalt and phosphorus—and works at an environmentally friendly neutral pH to release oxygen from water.
In this video , Daniel Nocera describes new process for storing solar energy.
Last year , MIT scientists developed the basis for a technology that could bring wireless convenience to battery recharging, allowing you to pack all those adapters into a drawer for good. The MIT team, with members from the school's physics, electrical engineering, and computer science departments, along with its Institute for Soldier Nanotechnologies [http://web.mit.edu/isn/], adapted known qualities of magnetically coupled resonance to transmit electricity from a power source to light a 60 W light bulb 7 ft away.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
